Nested property value de-referencing. Possible???

["Hawkins, Keith" <KH...@us.nomura.com>]

Say you have a property called env set to a value of "qa"  and you have a
property called qa.install.dir  set to /local/install/qa.

Is it possible to do something  like the following

	<property name="installDir"   value="${$env}.install.dir}" />
	<echo "Install dir = ${installDir} "/>

and have the echo spit out Install dir = /local/install/qa

If nested dereferencing is not possible, what is the standard ant approach
to handling these situations?

Thanks,
Keith

You need to use propertycopy from ant-contrib.
